{"version":"1.0","type":"rich","title":"Cheap tricks with interaction","description":"This example displays a world map rendered in SVG using D3 v5 and a Mercator projection, with country boundaries drawn from TopoJSON data. It demonstrates simple interactive techniques: users can pan and zoom the map via d3.zoom, while hovering over individual countries triggers a CSS-based color change and a native tooltip showing the country name, sourced from a TSV file. The code uses d3.geoPath, d3.geoMercator, and topojson.feature.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/df06e1c1707d4290ac8a9433a91268fa?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
